The comments came after the American leader said he has received encouragement from the leaders of China and Japan, and assurance that North Korea had promised not to shoot missiles in the interim, as he moves toward the high stakes summit, announced suddenly this week.

“I think North Korea is going to go very well, I think we will have tremendous success. We have a lot of support,” Trump told reporters before boarding his Marine One helicopter to travel to a rally in Pennsylvania.

“The promise is they wouldn’t be shooting off missiles in the meantime, and they’re looking to de-nuke. So that’d be great.”

At the rally, he told supporters that the United States had “shown great strength” when tensions were high with Pyongyang, but he went so far as to say the reclusive regime’s leaders “want to make peace.”

“I think it’s time,” Trump said.

He also boasted that his reducing the North Korean nuclear threat helped save the Winter Olympics that were held last month in South Korea.

“It’s a little hard to sell tickets when you think you are going to be nuked,” the President added.

Earlier, Trump said China’s President Xi Jinping was appreciative of his decision to opt for diplomacy rather than “the ominous alternative,” while Japanese Prime Minister Shinzo Abe was “very enthusiastic” about talks with North Korea.
